Thank you very much for your reply.
I saw the auction you are referring to, however this was the one I meant:
eBay Motors: PT Cruiser Coilovers NEW (item 290198196024 end time Jan-20-08 13:33:26 PST)
It shows the part number of 127 27 002.
It is the Mopar/KW kit, but the part number is a KW one.
The main reason I am looking at a coilover kit is so I adjust the rear height
(when I tow a waverunner). Do you think this set (the link) is rear adjustable?
The rear seat on this set appears to have threads.
Thank you for your help
